Sodium hypochlorite generator assembly structure

Sodium hypochlorite generator is generally composed of salt device, electrolytic device, rectification equipment, water mixing system, automatic control device and liquid storage tank. The core part, the electrolytic device, is composed of a group of ruthenium-iridium precious metal nano-coated special metal material as the anode, corrosion resistant special metal material as the cathode, forming a closed electrolytic cell container. In addition, the electrolytic cell is equipped with a backwash system and a cooling system.

The electrolytic cell of sodium hypochlorite generator is the key of sodium hypochlorite generator equipment. The electrolytic reaction and solution reaction of generating sodium hypochlorite are completed in it. The performance of the electrolytic cell determines the performance of the whole equipment. Electrolytic cell is generally composed of a tank body, sodium hypochlorite generator electrode group (titanium anode plate + titanium cathode plate + bipolar electrode plate). The electrode in the electrolytic cell is the conductor that the current enters or leaves the electrolyte, and the electrolytic process is the REDOX reaction on the interface of the electrode phase. The sodium hypochlorite generator electrode is divided into unipolar sodium hypochlorite generator electrode plate and bipolar sodium hypochlorite generator electrode plate according to the way of plate connection to the power supply. At present, the electrode structure of large sodium hypochlorite generator in China is mostly bipolar sodium hypochlorite generator electrode. Electrolytic parameters are generally current density, brine concentration, brine temperature, brine flow, etc. The operating effect index of sodium hypochlorite generator mainly includes effective chlorine concentration, power consumption, salt consumption and other operating costs.
